Can a VCD screw up a TV?

[Ghetto Pimp]

A friend of mine has converted & burnt his first ever VCD,when he played it on his standalone player (which works fine with the VCD`s ive always done him) his TV screen warped the picture & a third of the screen is missing.The worrying bit is when he put sky back on the picture stayed the same,he`s tried turning everything off & going through the settings on his TV but the picture is still screwed.
Anyone had this happen before?

Cheers.

sounds like he tried to put a PAL signal on NTSC tv or vice versa. tv shouldn't stick with it though

Does anything still display right?

How old is the Tv?? it might of been its time to go and just so happened to die when ur vcd was played.
However when he unplugged the sky he might have snapped a connection? or did something to the back?
ive never heard of a Vcd that kills tv, unless your friend fell asleep and left the tv on for 8 hours while the screen was frozen and the still image has burnt the tv?

Its just coincidence and most likely a vertical capacitor went finally bad.It usually takes a couple months of a static image to burn onto a tv screen.

Make sure the scart lead is plugged into the back of the TV ALL THE WAY!

The TV`s about 8 months old,i dont know what he did wrong but after converting with TMPGEnc he burnt it with nero and it gave him the non-compliant vcd screen,which he ignored & carried on burning.
No nothing diplays right now...my first thoughts were the same as lostbee and the thing just decided to die at that piont

i think its with the tv...never heard any case like that...i got lots of lots of friends who use recopied/burn vcd and they didn't report any case like that...

Where are you guys getting it can't do it? Of course it can.

Feed any older monitor a signal with a frequency it can't handle, more than a few will go out from it. The old 'Halt, catch fire" instruction on a poorly designed system from the 80's simply changed a video setting so the monitor would get a signal it couldn't deal with..


TV's are designed with specific capabilities. Most can tolerate even an out of bounds signal for a while. No telling what your friend's VCD did, or what his DVD player output in response to it. 99 out of 100 of your friend's type of TV may have even handled it for a while, his may have just had a weak circuit that went out when stressed. Or 100 of the TV's may have gone out, no telling how far off his VCD and DVD player combo was making the video signal.

Still could be it was just its time to go, and it should have handled it. But it's quite possible for the extra stresses involved to have done it. Many of these circuits are designed to operate at specific frequencies, feed it signals way off frequency and the operation is undefined if not fatal to the device..

I find it hard to believe that this could happen to a relatively new set(8 months old). Possible, maybe. Probable, I doubt it.

Why? I only mentioned older for monitors, because most newer ones have a wide bandwith and can handle about anything coming in. Even most modern TV's aren't so tolerant or well designed. Feed a 20 Hz or 200 Hz signal into every TV you meet instead of the 50 to 60 Hz they're designed for and you'll find a lot that don't take it very long at all. Don't let your experience fool you, your TVs rarely ever meet a signal that's out of spec is why they don't blow up, it's not because they're all bulletproof. There's a reason for the hefty fines the FCC can levy for broadcast stations that broacast out of spec signals, and the possibilty of breaking many people's TVs at once is it. Lessened now with more intelligent designs, but there are plenty of cheap or poorly designed TVs out there, even some new ones.

Garbage VCD and a DVD player that tries to output garbage instead of outputting nothing could easily screw up a set, more a problem with the DVD player though since it should tolerate garbage discs without doing anything wrong on the output side. Heck even if it just output PAL or something, PAL/NTSC into the other type of set will screw the occasional TV even though the standards are relatively close. Anything not what it's designed for of course puts stresses above normal on the operation of the set, so of course would have the possiblity of being the straw that broke the camel's back.

Might want to read through some troubleshooting reports at repairfaq.org and get an idea for just how poorly designed many consumer items are. Even the high end TV's tend to have a notable imperfection or two in design or manufacture. Some TVs need little more than a sneeze to go out, even if they'll work indefinitely as long as you don't sneeze at them.

Neither of us know what really happened here. You expressed your opinion and I did the same. That's all.

Mr. Vertical IC Driver go boom.

What a riot, this thread.

What part of

The TV`s about 8 months old

don't you understand ?

This one's 8 months old, not manufactured in the 80's.

[flaninacupboard]

you sure you didn't just lean on the 16:9 button on the remote?

[lordsmurf]

The DVD player isn't going to send a signal the tv cannot handle. Not most of them anyways. Torpedo that "bad signal" guess right now.

Coincidence or user error.

A VCD won't destroy it. Even my PC monitor will just turn off if I give it a hz it hates. Put it back to something else, comes right back on.
